BUTTON.

I Application filed July is,-

T 0 all whom it may concern.

Be it known that I, WVILHELM TUxHoRN, a subject of Germany, and residing at Stolberg, Rhine State, in the State of Prussia, Germany, have invented certain new and useful Buttons, of which the following is a specification.

My invention relates to improvements in buttons, and more particularly in buttons which are fixed tothev trousers or the like without sewing and by clamping action, and which can be removed from the trousers. Buttons of this type consist of a base part provided with a stem'having an enlarged portion, a top part, and a pressure or clamping member formed with elastic tongues adapted for clamping engagement with said stem. The object of the: improvements is to provide a button of this type which is provided with additional locking means for preventing accidental separation of the sec tions of the button. lVith this object in view my invention consists in the matters to be described hereinafter and particularly pointed out in the appended claim.

For the purpose of explaining the invention an example embodying the same has been shown in the accompanying drawing in which the same reference characters have I prlslng a base member having a headed 0.

been used in all the views to indicate corrcsponding parts. In said drawing,

Fig. 1, is a sectional view showing the parts of the button assembled,

Fig. 2, is a plan view of the top'plate with the other parts of the button removed and looking into the inner part of said plate,

Fig. 3, is a. detail view showing the looking member, and

Fig. 4, is a top view of Fig. 3.

In the example shown in the figures my improved button consists of a base member z the stem 71 of which is formed with an enlarged portion is, a top part or plate at having secured thereto a disk Z formed with a conical sleeve Z, and a clamping member or disk a. The plate m is formed with three concentric cut-out portions 6 in the form of sectors each having a tongue 7 projecting inwardly from the inner margin and at an 1923. Serial No. 653,150. 1

ing plate a is formed with three elastic tongues 22 arranged along a cone and formed at the bottom parts of their longitudinal margins with cut-out portions 9 providing 5 shoulders 12.. The breadth ofadjacent cutout portions is such that the tongues f can pass through the same. Adjacent to the.

plate a the tongues 71 are formed with a circumferential grooved.

The button is assembledin the usual way, the stem 2" of the base member c'flbeing inserted into the conical sleeve Z and the pressure member a being inserted from the opposite side with its tongues b passing through 6 the cut-out portions 6. The plate at is now engaged by the circumferential groove (Z i i the upper margin 0 of which bears onthe inner face of the plate m so that it can not be loosened by accident. Should this be the case, for example by wear of the margin 0' or the margins of the cut-out portions 6, the shoulders bear on the tongues f and lock the disk a and the tongues 72 as against being retracted from the plate on. found that high elasticity and safe locking is insured. by providing three tongues b. I claim:

A button of the character described comstem, atop member receiving the stem and including a plate having a series of concentrio openings and tongues projecting in wardly of the openings and a clamping member composed of a conical sleeve for receiving the stem of the base member and provided with longitudinal slots forming resilient tongues and with openings at the inner ends of the slots forming shoulders for engaging the tongues on the plate for 0 preventing accidental separationof the-top member and also provided with an exterior annular groove for receiving the plate, substantially as and forthe purposes set forth.

In testimony whereof'I hereunto aflix my h signature in the presence of two witnesses.
